Magnetic resonance imaging (MRI) has given inconsistent results when used as a non-invasive diagnostic tool for Creutzfeldt–Jakob disease (CJD). In order to understand this finding, we studied a hamster model of scrapie by in vivo MRI and histopathology. Vacuolation of neurones/neuropil and gliosis were found to correlate with hypo-intense and hyper-intense changes in the conventional T2-weighted MR images, respectively. These opposing effects were shown to give rise to normal images of a scrapie-affected brain undergoing severe neurodegeneration, and may underlie the variability of previous CJD MRI data.
